The US is to execute a female federal inmate for the first time in almost 70 years, the Justice Department said. Lisa Montgomery strangled a pregnant woman in Missouri before cutting out and kidnapping the baby in 2004. She is due to be given a lethal injection in Indiana on 8 December. The last woman to be executed by the US government was Bonnie Heady, who died in a gas chamber in Missouri in 1953, according to the Death Penalty Information Center. The federal execution of Brandon Bernard, who with his accomplices murdered two youth ministers in 1999, has also been scheduled for December.
